Does anyone know if the CT2800's I/O channel enable/disable jumper (JP1) affects the IDE CD-ROM connector as well, or only the audio I/O? That jumper does not enable/disable any kind of I/O channel... I had no idea, thank you so much for clearing this up. I was a little bit confused by it existing …

Hi all, Does anyone know if the CT2800's I/O channel enable/disable jumper (JP1) affects the IDE CD-ROM connector as well, or only the audio I/O? The IDE interface address selection jumpers (IDE100/101) do have an "IDE CD-ROM interface disabled" choice, but I'm just not sure if this is fully …

The case looks good. It's making your monitor and keyboard look yellow now. :) Those Viewsonic CRTs are classic, and 17" seems to be a good size without being terribly bulky. Have you checked if your motherboard has a Coppermine compatible voltage regulator? If it does, something like a P3-600E …

Having checked and rechecked cables and jumpers, and tried every possible cable combination at least twice each, I've put this unit aside and put the original CD drive back in (which works perfectly). I have another DVD drive on the way, so will test it at some point in the near future. Thanks for …

I had a similar issue once, turned out to be some weird jumper setting on the hard disk. Apparently, that particular hard disk had two settings for "Master". One was "Master without Slave" and the other was "Master with Slave". If the wrong setting was selected, neither the master nor the slave …

This happened to me once when I had the IDE cable plugged in upside-down. I thought the IDE controller was broken, but it was just that I was using an IDE cable without the orientation tab and didn't check. Yeah the orientation tab is a lifesaver. lol Fortunately the cables I'm using in this system …

Use a different DVD drive. Samsung did something to their later IDE drives that causes detection problems on some older motherboards. I have a 2005 drive from them that causes exactly the same behaviour as you describe on one motherboard, but works fine on another (later one). Yesterday I ordered …

If the DVD drive is hooked up by itself does it work? Are you using a 40 or an 80 conductor cable? The 80 conductor cables are more rigid and the wires are much thinner. With it being a newer drive, it might not like the older cables. If it is hooked up by itself it does not work, no. Oddly if the …

Unfortunately this is the only system with IDE that I have running right now, and I don't have an adapter to give it a shot in a more modern one. Do you think a short on the DVD's side could cause BIOS to flip out to such a degree?

I prefer non-flat for retro stuff ^^ I definitely get you. I do too, except in the case of a lot of Win 95/98 games (which that particular work in progress is aimed at). For DOS games, and especially 80s titles, the curved screen is part of the charm. This particular build is aimed more at like …

It might be possible to track down an old PSU from the early 2000s which still has -5V. As an example, take a look at this LC Power 550W which I bought recently. I don't think I have any sound cards which require -5V to test it though. I've been keeping my eyes open for an older ATX to be available …

It could be done with a small solderable breadboard. Even without, in fact. If you don't need fancy looks, take a screw terminal strip and call it a day. Yes, a clean mod would put everything inside the PSU itself, but for a beginner project let's not open that. I'm not aware of ATX-related …
